There is 10 continents, a North and South pole, one continent that is made up of thousands of large tropical islands around the equatore, and continent like africa that is both a desert at the top of it and on its bottom is a huge huge lush rainforest that hold meny meny plants and animals. Then there is a continent like South america, it lays on the south western side of the african like continent and like south america it is mostly all Rain forest. That is 5 of the continents.
Near the south pole lays 2 small continents only about the size of earth each that are warm in the summer but in the winters can get very cold depending on what side of the continent is closer the the equator, this is wear animals like mammoths and migrating dinosaurs live, plus meny other animals from diffrent time periods.
